django-tastypie ToOneField

Question

我似乎无法弄清楚如何让ToOneField在django-tastypie中工作。

>> pip freeze | grep django-tastypie 
django-tastypie==0.10.0 

这里是我的模型和资源（sample_territory总是空用下面的代码）：

型号

class Sample(ProjectModel): 
    name = models.CharField(max_length=255) 
    territory = models.OneToOneField(Territory, null=True, related_name='sample_territory')   

TerritoryResource

class TerritoryResource(ProjectResource): 

    class Meta: 
     queryset = Territory.objects.all() 
     resource_name = 'sample_territory' 

SampleResource

class SampleResource(ProjectResource): 

    sample_territory = fields.ToOneField(TerritoryResource, 'sample_territory', related_name='sample_territory', null=True, full=True) 

    class Meta: 
     queryset = Sample.objects.all() 

Answer 1

显然我不明白tastypie的属性字段选项。

https://django-tastypie.readthedocs.org/en/latest/fields.html?highlight=toonefield#attribute

在我的情况的解决方案是：

sample_territory = fields.ToOneField(TerritoryResource, attribute='territory', null=True, full=True)
